This is one of the reasons I'd like to see some of the major developers release some arcade style versions of their major franchises, Nintendo has no problem slapping Link in a crossbow shooter why not Lara Croft or Crash Bandicoot in some fun mini game?
I'd be content paying $2-$15 for demo size games that have the same type of unlockable achievements/trophies, weapons, characters, and upgrades as normal big budget titles receive. It would cut development time and offer more/varied content and if any games generate some buzz make a epic version of it.
